Frans,

Is there a way of turning on tracing without using a config file? i.e. if you wrapper stuff up in a COM object the whole App.config doesn't work to well.

Thanks John

The tracing facility of .NET checks the config file for trace listener definitions, so if you for example want to trace to a file, you've to setup the trace listener in the config file. I'm not aware of a way to define a trace listener in software (not writing one, but activating one ) instead of a config file.
